'Really cool' reflected Jürgen Klopp at the end of an incredible 5-4 victory against Norwich City on Saturday afternoon that left the Liverpool manager with a pair of broken glasses due to his team's last-minute celebrations.

Substitute Adam Lallana finally settled the Carrow Road clash in the Reds’ favour in the 95th minute, just seconds after it seemed Sebastien Bassong’s equaliser would see both sides take a point.

Roberto Firmino had put Klopp’s charges ahead but the Canaries responded emphatically, forging a two-goal advantage through a Dieumerci Mbokani backheel, Steven Naismith’s drive and a Wes Hoolahan penalty.

Momentum wildly swung again when Jordan Henderson converted clinically and Liverpool managed to go back in front as Firmino dinked in his second of the game and James Milner seized upon a loose backpass to make it 4-3.

Bassong threatened to ruin the comeback, only for Lallana to force home a dramatic winner in the final seconds that sparked collective joy which left the manager requiring a trip to the opticians.

“Until now my heart has been very stress-resistant, so I hope it stays like this!” Klopp said at his post-match press conference, attempting to assess the game.

“I’ve had a few games in my life similar to this, but not with a happy ending. I’ve had 4-4 two or three times and to win 5-4 doesn’t happen often.

“In the end we can be really happy with nearly everything – especially with the three points. A draw would have been deserved for both teams.

“We needed the last moment to get it [the win], but a few days ago we lost a game we shouldn’t have against Manchester United, so today we took something back and that’s OK.

“It was spectacular, wild, good football, and both teams had good moments. The start was not good, but then the first half was good after 15 minutes but we didn’t score the second goal.

“We conceded two after set-plays and then they got a third one directly after half-time, but then we started playing football and it was impressive.

“We scored the goals, conceded again off a second ball from a set-play – I can’t believe it – but then we tried one [more] time and Adam Lallana did it. Cool, really cool!”

Klopp felt Liverpool lacked luck in the manner some of Norwich’s goals were conceded but admitted his side will have to find ways to tighten up as they look to reach Wembley by overcoming Stoke City on Tuesday.

He said: “It’s easy to see, but today even though we [conceded] four goals off set-plays, we defended them better. It was unbelievable.

“They got all of their goals from the second balls at set-plays. Things like this can happen. We had a better formation, better organisation and did what they had to do – defended the first ball – but then they all stayed in the box.

“Now we’ve made different mistakes. We take this and if you win 5-4 it’s a funny story, but it’s not that funny and we have to solve it.”

Klopp added: “It’s not easy to create chances against us, everybody can see it. It’s not easy. I don’t think there were a lot. Manchester United had no chances. Arsenal had one or two but not as many as usual.

“It’s frustrating, of course, but today it’s OK because we scored five. Everybody knows you cannot make five goals all the time. That’s why I said, it makes me sound crazy when I say we defended better today.

“The first ball we defended better but then we made the next fault. That’s how life is: you [fix] one problem, you’ve got another one. Now we have to solve this and hopefully the two days to the Stoke game are enough for this.”

Reporters at the press conference were also keen for an update on the situation with the manager’s glasses.

He replied: “One of them is in the museum of Borussia Dortmund because we won for the first time against Bayern Munich and Nuri Sahin broke my first glasses. Today it was Adam, it’s broken.

“Usually I have a second [pair] but until now I couldn’t find it because it’s really difficult to look for glasses without glasses!

“I’m not sure if anyone [at the Anfield museum] will ask for them but I will keep them and we’ll see.”
